Variator Doppler SX86 Yamaha Aerox
Sport CVT Doppler SX86 - Perfect for well-tuned setups and sporty scooters.
Advantages of the Doppler SX86 tuning CVT
The SX86 variator from Doppler, here for 50cc scooters with Minarelli engine (horizontal + vertical, LC + AC), uses large 19×15.5 mm rollers to provide smooth shifting, consistent acceleration, and reduced vibrations while riding. The specially calculated ramp angles optimize acceleration and torque across the entire RPM range.
With the 3 included roller sets, you can tune the variator to your setup and riding style. If you need additional weights: CVT weights 19x15.5mm.
The variator can be used with or without an electric starter. Running it without the starter allows full use of the CVT’s range, ideal for maximum performance.

scooter CVT
Modern scooters are equipped with a continuously variable transmission, the so-called CVT, also called variator.
CVT Parts:
- Front pulley, movable. It contains the variator weights and has a special shape with an inclined surface to allow the V-belt to move freely up and down.
- Ramp plate: Holds the weights in place.
- Variator sleeve: Serves as a bearing for the variator, which moves axially back and forth, i.e., opens and closes.
- CVT roller weights: Adjustment weights that play a critical role in function and performance.
original, Sport and Oversize CVTs
- Original: Original or OEM quality CVTs are equipped with a restrictor to limit the speed to 45km/h. There are riders who remove the restrictor to derestrict their scooter and unleash the full performance without restrictions.
- Sport: Sport CVTs are lighter than the original and are characterized by special angles and a special coating, which increases the top speed, but especially acceleration.
- Oversize: Based on the same principle as the Sport CVT, but has larger dimensions. With an oversize / overrange vario, the performance of the scooter can be increased even further.
You should also always replace the V-belt when replacing the CVT or go for a complete CVT kit.
